Unexplained Phenomenon of the Day

The city of Clintonville, Wisconsin, has been unable to explain a series of loud noises that started earlier this week and have occurred multiple times since.

The sounds have been described by locals as resembling "thunder, fireworks or someone slamming a heavy door."

Officials have set up recording equipment in an effort to find the source of the "booming sounds" that have reportedly roused residents from their sleep. That effort has been unsuccessful thus far, as has every attempt to explain away the mystery with manmade causes.

City administrator Lisa Kuss said they have so far ruled out water, sewer, gas, landfill, military, and mining-related origins, as well as known geological phenomena.

vibration-detection devices, set to be installed by Friday, will be used to determine the clamor's episcenter.

A city meeting has been called for 6 PM this evening. A Q&A session will be held, but Kuss has already acknowledged that there is no new information to disseminate at this time.
